Abstract

A method, computer system, and a computer program product are provided for authenticating a user. An image of a skin portion of the user is obtained. One or more landmarks are identified from the image obtained. The landmark includes at least one skin anomaly. Each identified landmark is analyzed at least with respect to location, form, dimensions and distances between landmarks and body parts. A unique signal is generated based on the identification and analysis of one or more landmarks. The unique signal is then stored for authentication of the user.

What is claimed is: 
     
         1 . A method of authenticating a user, comprising:
 obtaining an image of a skin portion of a user's body;   identifying one or more landmarks from said image associated with said skin portion of said user, wherein a landmark includes at least one skin anomaly;   analyzing said one or more identified landmarks at least with respect to location, form, dimensions and distances between one or more body parts or one or more other landmarks;   generating a unique signal based on said identification and analysis of any of said one or more identified landmarks; and   storing said unique signal for authentication of said user.   
     
     
         2 . The method of  claim 1 , further comprising associating said generated unique signal with said user in a user profile. 
     
     
         3 . The method of  claim 1 , wherein there are a plurality of users and said unique signal includes a combination of several users or a combination between at least two different landmarks associated with at least one user. 
     
     
         4 . The method of  claim 1 , wherein there are a plurality of landmarks identified for said user and said unique signal is provided by generating a numerical sequence of said one or more identified landmarks. 
     
     
         5 . The method of  claim 4 , wherein said numerical sequence further comprises providing a sequence of each one or more identified landmark presentation in a particular order having at least one repetition. 
     
     
         6 . The method of  claim 4 , wherein said user will not be authenticated unless said numerical sequence is provided. 
     
     
         7 . The method of  claim 1 , wherein analysis of a landmark location includes identification of said one or more landmark in relation to distance to a user body part. 
     
     
         8 . The method of  claim 7 , wherein said distance is measured in three dimensions and distances between any other identified landmark(s) in proximity as identified. 
     
     
         9 . The method of  claim 7 , wherein said distance is measured in three dimensions and distances between each proximal other body parts as identified. 
     
     
         10 . The method of  claim 1 , wherein analysis of a form and dimensions of said landmark includes said landmark(s) three dimensional measurements including any angles. 
     
     
         11 . The method of  claim 10 , wherein said dimensions include its measurements in all X, Y and Z directions and any angles of attachments of a raised landmark to a body part. 
     
     
         12 . The method of  claim 1 , wherein said image is obtained from a video or a live streaming broadcast. 
     
     
         13 . The method of  claim 1 , wherein said image is obtained from a smart device. 
     
     
         14 . The method of  claim 4 , wherein said unique sequence is stored and associated to said user, further comprising authenticating said user by comparing a user's current image with that of said previously stored sequence connected to said user. 
     
     
         15 . The method of  claim 1 , wherein said user is authenticated when entering a virtual environment or changing from one virtual environment into another virtual environment or into a real environment. 
     
     
         16 . A computer system for authenticating a user, comprising:
 one or more processors, one or more computer-readable memories and one or more computer-readable storage media;   program instructions, stored on at least one of the one or more storage media for execution by at least one of the one or more processors via at least one of the one or more memories, to obtain an image of a skin portion of a user's body;   program instructions, stored on at least one of the one or more storage media for execution by at least one of the one or more processors via at least one of the one or more memories, to identify one or more landmarks from said image associated with said skin portion of said user, wherein any landmark includes at least one skin anomaly;
 program instructions, stored on at least one of the one or more storage media for execution by at least one of the one or more processors via at least one of the one or more memories, to analyze said one or more identified landmarks at least with respect to location, form, dimensions and distances between a user's body part(s) or one or more other landmarks; 
   program instructions, stored on at least one of the one or more storage media for execution by at least one of the one or more processors via at least one of the one or more memories, to generate a unique signal based on identification and analysis of any identified one or more landmarks; and   program instructions, stored on at least one of the one or more storage media for execution by at least one of the one or more processors via at least one of the one or more memories, to store said unique signal for authenticating said user.   
     
     
         17 . The computer system of  claim 16 , wherein said there are a plurality of users and said unique signal can include a combination between several users or a combination between at least two different landmarks associated with said user. 
     
     
         18 . The computer system of  claim 16 , wherein there are a plurality of landmarks identified and said unique signal is provided by generating a numerical sequence of said one or more landmarks. 
     
     
         19 . The computer system of  claim 18 , wherein said unique sequence is stored and associated to said user, further comprising authenticating said user by comparing a user's current image with that of a previously stored sequence connected to said user. 
     
     
         20 . A computer program product for authenticating a user, the computer program product comprising:
